摘要

A shift about 0.3eV to higher binding energy is reported in the valence band and Cls core level of Kx C_(60)(x<0.2).Analysis shows that the result could not be interpreted by a mixture of C_(60) and K3 C_(60).A dulite K-doped phase and fermi level pinning near the lowest unoccupied molecular orbital derived band caused by K-doping are proposed.
